Connection Label

Virtual connection between circuit envelope ports

Description

The Connection Label block lets you specify virtual connections between circuit envelope ports, similar to the Goto and From blocks in Simulink^® diagrams. These connection lines are nondirectional, which means that all sides of the virtual connection use the same type of block.

Virtual connectivity is established by the label name. If two or more Connection Label blocks in a model subsystem have the same label, then the circuit envelope ports of other blocks connected to them behave as though they were physically connected. Virtual connections cannot cross subsystem boundaries. The label name is displayed next to the block icon on the model canvas.

You specify the label name by using the Label parameter.

Use the Connection Label block to reduce diagram clutter by breaking off tangled connection lines.

You can select a Connection Label block to highlight blocks related to it. To show a related block in an open diagram or new tab, pause on the ellipsis. Then, select Related Blocks from the action bar. When multiple blocks correspond to the selected block, a list of related blocks opens. You can filter the list of related blocks by entering a search term in the text box. After you select a related block from the list, window focus changes to the open diagram or new tab that shows the related block.

Examples

Create Virtual Connections Using Connection Label Block

Use a Connection Label block to create a virtual connection between two conserving ports.

Ports

Input

Port_1 — Connection port
untyped circuit envelope port

Circuit envelope connection port. By default, this port is untyped.

You define the port type by connecting this port to a circuit envelope port of another block in the subsystem. Once you establish a connection, other Connection Label blocks that are in the same subsystem and have the same label can be connected only to the same type of port.

Parameters

expand all

Label — Name of connection label
`Label1` (default) | character vector | string

Label name, which establishes the virtual connection. If two or more Connection Label blocks in the same subsystem of a model have the same label, then the circuit envelope ports of the blocks connected to them behave as though they are physically connected.

The value of this parameter appears as a label next to the block icon on the model canvas.
